Toripalimab, bevacizumab, and irinotecan in dMMR/MSI locally advanced colorectal cancer: First-stage results from a phase 1b/2 trial.
Trial report in Cell reports. Medicine, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. It is linked to trial NCT04988191 (The Efficacy and Safety of Toripalimab Combined With Bevacizumab and Chemotherapy as Neoadjuvant Therapy in Patients With Advanced MSI-H or dMMR Colorectal Cancer), which is not on this map.

What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.

Abstract
This is the first stage of the phase 1b/2 trial evaluating the effectiveness and safety of toripalimab, irinotecan, and bevacizumab in patients with rectal cancer refusing up-front surgery or radiation therapy (rectum cohort) and patients with T4NanyM0 colon cancer (colon cohort) with deficiency of mismatch repair (dMMR) or microsatellite instability (MSI). This trial allows a doctor-patient shared decision-making process to determine whether to omit irinotecan or bevacizumab and the optimal surgery timing. The primary endpoint pathological complete response (pCR) rates in the full analysis set (FAS) and per-protocol set (PPS) are 57.1% (95% confidence interval [CI] 28.9-82.3) and 66.7% (34.9-90.1), respectively, in the colon cohort (n = 14) and 75.0% (35.6-95.5) and 100% (51.7-100.0), respectively, in the rectum cohort (n = 8). No disease recurrence occurs in PPS. No grade 4-5 drug-related adverse events are observed. Toripalimab with or without irinotecan and bevacizumab shows promising efficacy and manageable toxicity in dMMR/MSI T4NanyM0 colon cancer and locally advanced rectal cancer (ClinicalTrials.gov: NCT04988191).
